It's a bragging link for those who cotton to it. It's part of the "Surprise Me" (Fun mode) box function and you can read about it here lol :D http://en.blog.wordpress.com/2010/04/17/surprise-me/
It used to produce a silly video but I don't know what it does now as I immediately disabled it.
By unchecking the ___ Fun "surprise me" feature which was on by default I got rid of it all. See here >
